Product Description

Singclean Procalcitonin (PCT) Test Kit (Fluorescence Immunochromatography) for infection detection

Product Description


Procalcitonin (PCT) is the prohormone of calcitonin (CT), which is generally less than 0.1ng/mL in the blood of healthy people, and its secretion increases after being stimulated by pro-inflammatory responses, especially after bacterial infection. Procalcitonin is an important marker that can specifically distinguish bacterial infection from inflammatory response caused by other reasons. Viral infection, allergy, autoimmune disease and transplant rejection do not cause significant elevation of procalcitonin, while local bacterial infection can result in moderate elevation of procalcitonin concentrations. In some cases (neonatal, multiple trauma, burns, major surgery, prolonged or severe cardiogenic shock), the elevation of procalcitonin may not be related to infection and usually returns to normal values quickly.
PCT is an ideal indicator for the auxiliary diagnosis of severe bacterial infection and septicopyemia, sepsis and other diseases, and has high sensitivity and specificity for systemic bacterial infection, septicopyemia, sepsis, etc.


Indications for Use

The test kit is used for the quantitative determination of procalcitonin (PCT) in human serum, plasma or whole blood samples in vitro.

Specimen Collection

1. Xihu (West Lake) Dis.n serum, plasma or whole blood samples; other body fluids and samples may not give accurate results.

2. Venous blood or fingertip blood should be collected under sterile conditions. It is recommended to use human serum or plasma for testing.

3. Anticoagulation with EDTA, sodium citrate or heparin is recommended for plasma and whole blood samples.
4. After the clinical blood samples are collected, the test must be completed within 4 hours at room temperature; serum and plasma can be stored at 2~8°C for 3 days and stored below -20°C for 5 months. Whole blood samples should not be frozen and stored at 2~8°C for 3 days. Avoid heat inactivating samples, and hemolyzed samples should be discarded.
5. Samples must be returned to room temperature before testing. Cryopreserved samples need to be completely thawed, rewarmed, and evenly mixed before use. Do not CZPT and thaw repeatedly.


Test Procedure:

a) Bring the test kit and sample to be tested to room temperature.
b) Make sure the ID card matches the batch number of the kit, and insert the ID card into the card reading area of the instrument to read the information.
c) Open the inner package of the test card, take out the test card; draw 70μL of serum plasma sample, drop vertically to the test card sampling place, and start timing; draw 70μL whole blood, vertically drop it to the test card sampling place, and immediately add 1 drop whole blood diluent at the sample adding place and start timing.
d) After adding the sample, click “Start Test” on the screen of the fluorescence immunoanalyzer, and the test card will react at room temperature for 10 minutes; insert the test card into the test card slot of the fluorescence immunoanalyzer, and the instrument will automatically test the test card; The test results can be seen on the display screen of the immunoassay analyzer. Click “Print” on the screen to print the results.

Positive Judgment Value or Reference Interval
Reference value: <0.5ng/mL. The reference interval for plasma and whole blood samples is the same as that for serum samples. Due to differences in geography, race, gender and age, it is recommended that each laboratory establish its own positive judgment value or reference interval.

Interpretation of Results
(For reference only, not used as clinical diagnostic criteria, test results need to be combined with other clinical and laboratory data for clinical diagnosis)

PCT mass concentration (ng/mL) Clinical significance
<0.05 Normal value
<0.5 No or mild systemic inflammatory response. May be local inflammation or local infection.
0.5-2 Moderate systemic inflammatory response. Infection may be present.
2-10 Most likely sepsis, severe sepsis, or septic shock. There is a high risk of organ dysfunction.
≥10 Almost all severe bacterial sepsis or septic shock. Often accompanied by organ failure, there is a high risk of death.



a) This kit is only for the test of human serum, plasma or whole blood samples. Abnormal hematocrit samples have an impact on the results of the whole blood test. The test results of serum, plasma and whole blood are not significant difference when the hematocrit is between 21% and 48%.
b) The test results need to be combined with other clinical and laboratory data, and if the PCT test results do not match the clinical assessment, further testing is required.
c) False positive results may be caused by: cross-reaction of antibody-like components in the blood; some nonspecific components in blood have similar antigenic determinants to capture fluorescent-labeled antibodies.
d) Hemoglobin, triglycerides and bilirubin in the blood sample can interfere with the test results, where the maximum allowable concentrations are 5g/L, 10g/L and 0.2g/L, respectively.
e) False negative results may be caused by: some unknown components shield the antigenic determinants from binding to the antibody; the unstable PCT antigen gradually degrades with time and temperature and cannot be recognized by the antibody. Valid test results depend on a good reagent and sample storage environment.
f) Other factors may also cause errors in test results, including technical reasons, operational errors and other sample factors.

How to Properly Lubricate a CV Joint

Having a CV joint in your vehicle is essential if you are looking to maximize the power output of your front or rear axle. A CV joint is a type of constant-velocity joint that transmits power through a variable angle. It is used in front-wheel drive vehicles. Unlike a constant-ratio joint, a CV joint does not increase friction.

Lack of lubrication

Using CV joint without proper lubrication can cause damage to the joint and may result in your car being unsafe to drive. If your car’s CV joint has been damaged, you can have it repaired at a local mechanic.
A CV joint is an important component of your car’s suspension system. It is designed to transfer motion from the transmission to the wheels. It is made up of two joints: an outer joint and an inner joint. The outer joint connects the driveshaft to the wheel, while the inner joint connects the driveshaft to the transmission.
The joint’s grease can leak out, and this can cause excessive friction. This may result in noise from the CV joint when you start your engine or when you turn a sharp turn. You may also notice a clicking noise. You should also check for signs of corrosion in the joint.
A CV joint may also fail because of wear and tear. It is a durable component, but it will not last forever. It is important to inspect it regularly to avoid causing more damage.
If you notice a lot of noise from the CV joint, you may want to have it repaired. This can be caused by a worn joint or a faulty CV boot. It is best to have it repaired before the lubrication becomes too thin and is no longer effective.

Torn or damaged CV boot

Getting your hands on a torn or damaged CV boot can be a real pain. However, there are some tricks of the trade you can try out before calling it quits. One of the easiest ways to do it is with a small screwdriver and a few minutes of your time. If you’re lucky, you might even end up with a new set of wheels!
The first step is to find out what you need to replace. This can be done by removing the front and rear hubs, aka the CV axles. Once you’ve got them out of the way, you can start to replace the bearings. The process should take no more than an hour per side, depending on your car’s particulars. You can even take a break and have a beer on the house while your work is done. After all, you’ve just had a major automotive repair done.
The biggest problem is finding the right tools to do it. You’ll also want to look around for a competent mechanic, and a spare set of eyes to watch over your shoulder. Depending on your car’s particulars, you may also want to check out a CV boot repair kit. You’ll also want to be on the lookout for any leaking fluids from the front differential. The most common culprits are brake fluid and power steering fluid, but there are many more to choose from.

Larger tyres

Changing your tyres is one of the better ways to improve your ride. For one, you will not have to worry about a plethora of road debris, i.e., rocks, grit and grime. The result is a much more pleasant ride and a better environment for your passengers to enjoy. Moreover, you’ll save yourself some cash in the long run. This is because a properly maintained set of tires will last much longer than their cheap counterparts. A side-by-side comparison of similar tires will give you an idea of just how much money you can save. This is not to mention the added bonus of improved braking performance.
While you’re at it, swap out the cheap ol’ tyres for some high performance rubber and you’ll enjoy a much improved ride for years to come. Not only that, but you’ll also reap the rewards of better gas mileage. The best part is, you’ll be rewarded with a better looking car as well. After all, who wants to spend time in the shop repairing something that is not actually improving the driving experience?
A good time to check out your local tire shop for a snazzy new set of tires is a nice rainy day.

Lifting your 4X4

Using a CV joint to lift your 4X4 can be a good idea if you’re looking to increase ground clearance or add traction. Unfortunately, this can cause premature wear to the CV joint. To avoid this, you should take steps to protect the CV joint as much as possible.
If you’re considering using a CV joint to lift your 4X4, there are several things you need to know. CV joints are part of your suspension system, and they connect your engine to the wheels. There are many different types, and they each have different working limits. You should also take into account the materials used, as well as the range of lift.
CV joints are often used on IFS 4x4s, but they’re not the only option. Other options include leaf springs and coil springs. You can also use a suspension lift kit. This will allow you to increase the height of your vehicle and fit bigger tyres. These can increase your ground clearance, traction and visibility. However, they can also be expensive and require significant modifications to the suspension.
The largest benefit to using a CV joint to lift your 4X4 is the increased driveline strength. However, it can also cause your CV joints to fail prematurely. The joints need to work at a larger angle than usual to accommodate the added weight. A lift under two inches will usually be within the original tolerances of the 4×4.
If you want to lift your 4X4 with a CV joint, you should first determine the type of CV joint you need. There are many aftermarket companies that offer competition-spec chromoly CV joints, but only a few in Australia.

Blown CV Axle

cv joint
Having a bad CV Axle can cause a car to run poorly, which can also lead to serious personal injury. The best way to diagnose whether your vehicle is suffering from a bad axle is to have it inspected by a professional.
The CV axle is a direct link between the wheels and the transmission, and as such is subject to heavy stress. It can wear out quickly, causing the car to make loud noises and be difficult to control.
If your CV axle is making noises when turning, it may be suffering from a damaged joint. If the joint is damaged, the shaft could break away from the wheel, causing serious damage. This can be dangerous if you are driving at speed and need to avoid hitting something.
When your CV axle is damaged, it can also cause you to pull to one side, which may indicate that it is out of alignment. The axle is also susceptible to damage from water. This can cause corrosion and rapid wear.
A worn CV joint can also cause excessive vibrations while accelerating. This can intensify as you accelerate, making it difficult to control the car.
In addition, a bad CV axle can make a loud, scoring sound when it runs. It is best to have it checked by a mechanic.
You may also hear a clicking noise when turning. This is most often heard during sharp turns at low speeds. If your CV axle makes a clicking noise when turning, it is likely that the joint is damaged.
In addition to clicking noises, a bad CV Axle can cause your car to make knocking or knocking noises. This may sound like a normal knocking noise, but it is a sign that the axle is wearing out.
